Curious.
When the wife works and the guy (really) learns, it is a positive thing in all directions. What have women been fighting for, for who knows how long: the equal right to work. They make money, and gain great respect and status. This might infringe on a marriage, because the husband may feel like a loser. But if the husband is really shtieging away and the husband and wife appreciate each other, it’s a beautiful thing.
This does not mean that the wife has to do it. It just means that it is a valid approach.
